A kind of preparation method of foamed concrete cushioning anti-collision structure

Abstract

The invention discloses a preparation method of a foamed concrete buffer anti-collision structure, relates to the technical field of civil engineering, and in particular to the field of the preparation method of the foamed concrete buffer anti-collision structure. The preparation method aims to solve the problems that an existing buffer anti-collision structure is not obvious in energy absorptioneffect and poor in anti-collision effect. The preparation method of the foamed concrete buffer anti-collision structure comprises the following steps of, mixing the catalyst DMP-30 with polyether polyol, and then dropping the DABCO-33lv catalyst by using a rubber head dropper so as to obtain a white material mixture for later use; 2, taking polyisocyanate, mixting the white materials and the cement, stirring at a constant speed and controlling the temperature to be unchanged, meanwhile, adding into a shaping die, and then forming the foamed concrete plate with a plurality of equal-spacing third through holes; and 3, assembling the concrete plate prepared in the step 2 with a mounting plate, a base soil layer and a metal mesh structure, a spring, a fixing plate and the like in sequence to obtain the foamed concrete buffer anti-collision structure.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to the field of preparation methods of foamed concrete buffer and anti-collision structures. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water, admixtures and admixtures in a certain proportion, and stirred, also known as ordinary concrete. It is widely used in civil engineering. [0003] The design of the anti-collision device needs to be comprehensively considered according to the anti-collision ability of the pier itself, the shape of the pier, the tonnage of the vehicle or the type of the ship, the collision speed, the collision energy and other fa...
